Flowing water eats away at the soil on the lower bank along the outside curves of rivers. The water is piled against the outside of the curve as the river bends, similar to the sensation of being pushed to the outside of a fast-turning car. This flowing water scours material away, causing the bank to collapse. A common and effective method of preventing erosion is to armor the bank with a robust layer of material that cannot easily be moved or washed away by the current, such as rock. This results in a bank armored against erosion, but it does not allow vegetation to flourish on the part of the bank covered in rock. It also doesn't help dissipate the energy of that flowing water, which can then be exacerbated downstream. It often requires the entire armored length to be clear-cut and graded.
An alternative to armoring is to redirect the river's flow from the outer bank, thereby preventing scour through deflection. An effective way to do this is to angle rock barbs or weirs upstream into the channel. This forces the water to flow around and over at a perpendicular angle. This pushes the main flow back towards the center of the stream rather than along the outer bank. Often, a deep pool is made just off the end of the weir towards the center of the channel. This causes variable flows and depths within the channel that fish and other organisms like. ACD has recently implemented bendway weirs and plans to install more in the near future.

A rain garden was recently completed to benefit water quality in Coon Lake. This is the third rain garden in that neighborhood, each treating stormwater from a different section of the street. Previously, all curbside runoff was piped to the lake. This project was a collaboration between the Sunrise River Watershed Management Organization, ACD, and the landowner. Funding was from a grant from the Clean Water, Land, and Legacy Amendment.
Thanks to the Volunteers, Conservation Corps, and Three Rivers Park District staff for joining the ASP Rare Plant Rescue team to rescue state threatened Viola lanceolata, state Endangered Carex pallascens, and state Threatened Trichophorum clintonii from an area that will be dug up and developed soon. Those plants will temporarily grow at the MN Landscape Arboretum during the hot summer. In the fall, we will plant them into ecologically appropriate habitats on protected lands where they will be monitored.
Stay tuned for a volunteer planting event in the fall. Sign up to be added to the Volunteer List. Learn more about the ASP Rare Plant Rescue. For more information, contact Carrie Taylor, Restoration Ecologist, at
Vernal pools are shallow wetlands that fill with water in the spring and fall, then often dry out in the summer. They may appear like large puddles, but these depressions are brimming with life and help improve water quality. By capturing water from snowmelt and heavy rainfall, vernal pools reduce the amount of runoff (and therefore the contaminants it carries) reaching nearby surface waters and developed lands. This lowers flooding risks, improves water quality, and contributes to groundwater recharge as the trapped water slowly infiltrates through the soil.
Vernal pools rarely contain fish because their water levels fluctuate dramatically. This creates a safe haven for many amphibians and aquatic invertebrates that would otherwise be heavily preyed upon. While some depend on vernal pools during only their vulnerable egg and larval stages, others spend their entire life within or near them. These small wetlands also provide food, water, and refuge for many other wildlife species such as ducks, turtles, and snakes. Benefits stem beyond the pool itself as several aquatic insect larvae transform to flying adults, serving as forage for insectivores like songbirds and bats.
Vernal pools are highly sensitive to environmental changes. Because they are nearly invisible for much of the summer, they can be easily missed and destroyed if the land is modified. You can help protect vernal pools on your property by noting their boundaries when visible in the spring and avoiding disturbance throughout the year. This is also a great time to explore the abundance of wildlife in and around these wetlands! For more information contact Breanna Keith, Water Resource Specialist, at

ACD has secured over $78,000 - including $71,000 in state Watershed-Based Implementation Funds and $7,100 in local matching funds from the City of Fridley - to revitalize aging rain gardens in the Coon Creek Watershed.
Many rain gardens are now beyond their original 10-year lifespan, yet still hold potential for managing urban stormwater runoff. This project will remove accumulated sediment, repair infrastructure, and improve plantings within up to 10 rain gardens. The work will increase the rain gardens' ability to capture and filter pollutants from stormwater runoff, thereby reducing phosphorus by an estimated 5.2 pounds annually for the next decade.
These efforts represent targeted investments in existing infrastructure to provide cost-effective water quality benefits. Existing rain gardens in the Coon Creek Watershed that are 10+ years old will be analyzed, and those with the most benefit potential will be revitalized. Maintenance agreements will help ensure long-term success.
Work will begin in 2025 with site analysis, potential benefit estimates, ranking, and site selection. Designs, bidding, and rain garden revitalizations will follow. For more information, contact Mitch Haustein, Stormwater & Shoreland Specialist, at
Designs have been completed and construction planning is underway for nine shoreline restorations on Martin, Coon, and Linwood lakes in Anoka County. Sites were selected based on the severity of erosion, and therefore the amount of nutrients and sediment they're contributing to the lake. A variety of 'bioengineering' approaches will be applied, utilizing natural materials such as vegetation, wood, coir logs, and rock to stabilize the shoreline while enhancing habitat for fish and wildlife. Funding is provided by a Clean Water Fund grant, the Sunrise River Watershed Management Organization, and landowner match. Stay tuned for more updates!

The 2026 budget request to Anoka County includes adding a Groundwater Specialist to ACD's staff. This is the third consecutive year that this need has emerged as a top priority. Anoka County has never had a professional dedicated solely to managing our groundwater. Given our situation, it's time to shift our priorities. What situation?
This combination of factors can come together in troubling ways.
If only we had a Groundwater Specialist at ACD, we could:

When confronted with something eating your prized tomato plant, sometimes our first instinct is to pick up the bottle of pest spray. Oftentimes, we don't even realize that the plants we've purchased contain neonicotinoids, which are systemic (within) the plants' leaves, stems, flowers, nectar, and fruit. These 'neonics' are highly effective in killing pests, but they lack discrimination, and mounting evidence suggests they are contributing to the decline in pollinator numbers. An alternative is called IPM or Integrated Pest Management. The concept is to address pest infestations as they occur and manage pest damage on an as-needed basis, rather than chemically on a predetermined schedule.
Cultural practices may include:
Biological and habitat controls include:
When nothing else works and damage levels warrant continued action, research the organic and manufactured chemical options for the specific pest in question. Insecticidal soaps are a good option for many sucking and chewing pests. Neem oil is similarly safe on food with no dangerous residues while killing or reducing pests, powdery mildew, and other fungal infestations. If all else fails and traditional pesticides are used, follow label directions carefully, use them minimally, and avoid spraying open flowers and applying them during the day when pollinator activity is highest.
The Harder Path is the Right Path
As is often the case, the more convenient approach — using neonicotinoids and other chemicals on a widespread basis in anticipation of pest problems — is seductive but ultimately harmful in the long term. Damage to pollinators, faster evolution of resistant pests and replacement of natural processes with chemicals are all costs that eventually have to be faced. The IPM approach requires more work and acceptance of a certain amount of pest damage. We must reduce and manage the use of neonicotinoids and other agricultural chemicals, as their long-term impact will be far more harmful than beneficial. Do it for the bees. Do it for the butterflies. Do it for the birds. Do it for you.

ACD is seeking a group, company, or individual to provide $1,000 per year in support for the St. Francis High School biomonitoring program. Our past sponsor has had to withdraw due to financial constraints. Each year, we take high school biology classes to the Rum River to catch and count macroinvertebrates (bugs, crustaceans, etc.) that live there. Because some of these critters require high-quality conditions, we can use them to calculate metrics of river health. It's hands-on education led by professionals, with implications beyond the classroom. This program has been going since 2001. 1,950 students (average 81/yr) have donned waders, grabbed a net, and learned about the Rum River.
Financial assistance is used to help cover the costs of waders, nets, and other necessary equipment. It also ensures that our natural resource professionals can provide instruction and help students discover what their data means. Any group willing to provide financial assistance can please contact
An early thaw and record-breaking warmth have turned the typical spring emergence of ticks into an explosion of them. Anoka County is a high-risk area for tick born disease according to the MN Dept. of Health. The two primary types of ticks Minnesotans are likely to pick up afield are American dog (wood) ticks and Blacklegged (deer) ticks. While wood ticks can transmit disease to humans, it is rare. Blacklegged ticks (or deer ticks) however, carry a bevy of diseases transmittable to humans. Some of these diseases can cause lifelong illness and suffering. Luckily, there are some easy strategies to implement while outdoors to reduce your chances of being bitten and infected:
1. Treat clothing with Permethrin. Unlike typical "bug spray", permethrin is used to treat clothing before going outdoors. It should not be applied to the skin. Permethrin is the most effective deterrent against ticks, and it also keeps mosquitoes and flies away.
2. Wear long pants, sleeves, and boots. Tuck your pants into your socks and shirts into your pants to reduce openings to your skin. Light colored clothing makes ticks easier to see.
3. Try to stick to mowed areas or trails if possible.
